A friend woodwork (Iwata-300), 12BR70.

Nice design and woodwork.

Do you know what drivers are mounted on the Iwata-300's?

Beyma CP750/Ti

Beautiful woodwork.

This is Palisander Rio. Because of limited time shape is kept simple but in future who knows.

phusis · 2nd March 2012, 06:59 PM

Beautiful wood finish.

That's one mean looking horn/driver combo. Have you heard any of them(horn and/or driver), jzagaja, in whatever combination - and if so, some impressions?

CP750/Ti on Iwata is IMHO too sharp. Large titanium diaphragms ring too much - should be damped for home use.

That's what I feared.

The BMS 4590 coaxial driver would likely make a good combo with the Iwata horn, I presume?

Does anyone have any polar plots of the BMS4590/92? Reaching flat to 20 kHz on axis is one thing, doing so with good power response is another.

Edit: I meant the polar response on big horns like Iwata 300 or Tractrix 450 that can play low.

True no magic here. Opinion from Radian users are welcome. Next week I will be measuring JMLC-200T + Radian 950 with Truextent.
